"Electronic Pickup Unit" for Asynchronous Generators  


    EPU stands for Electronic Pickup Unit (in association to MPU the Magnetic Pickup Unit).
    The EPU-100 receives the electrical signal and converts it into a "MPU signal". This information about the speed of rotation of the asynchchronous generator can be fed into a genset control (for example an easYgen). So the genset control can decide for connecting the asynchronous generator to the mains/utility. Woodward's EPU-100 is particular suitable to work with the very small voltage (as low as 0.5 Vac and as high as 600 Vac) a asynchronous generator produces until it’s breaker is closed.

    EPU-100 is a small plug and play device that requires no configuration or adjustments. In combination with Woodward’s easYgen genset controllers, it provides an ideal solution for asynchronous generator sets. The easYgen comes with a dedicated asynchronous firmware implemented by delivery and setup for MPU signal coming from EPU-100 is just a few parameter settings away.

    This standard DIN rail mounted device contains an LED for easy diagnostics.
    The wiring printing on the housing makes it very easy to install it. 

     Features include:

    • Simple plug and play converter
    • Easy and convenient to install, operate, and diagnose
    • Seamless integration with Woodward genset controls
    • CE marked
